Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

slope = Δy/Δx = 6/2 = 3

At a certain fast-food restaurant, 69 % of customers order a chicken sandwich, 46 % of customers order french fries, and 36 % of

Leviafan [203]

We have events:

A - customer orders a chicken sandwich
B - customer orders french fries

and probabilities:

$P(A)=0.69\\\\P(B)=0.46\\\\P(A\cap B)=0.36$

so:

$P(A\cup B)=P(A)+P(B)-P(A\cap B)=0.69+0.46-0.36=\boxed{0.79}$

What equation can be used to find the length of AC

Leno4ka [110]

I'm pretty sure this is the answer:
(10)sin(40°) = AC

It's sin becasue it needs the opposite side of 40° and has the hypotenuse.
